S20 plus display issue

[Anonymous]

Recently I have noticed that there is some colour calibration issue on my phone, not sure if this is software side or hardware side issue. 

The left side (around 1/4 area vertically) is darker in comparison to the remaining screen.

It is most visible on grey colour and on low brightness only(35% and below) and I noticed it while on dark mode. 

Now I don't know whether the left side is the true colour or the remaining area is. 

It's really bothering me and sadly because of countrywide lockdown i can't even take it to a service center.

Anyone else facing this issue?

I noticed this same issue. I use dark mode and at night in low brightness the vertical right 1/4 of my screen is off color. When I turn up the brightness it goes away.  I am not sure if this is a software or hardware issue. It seems you have the same situation as I do, hopefully it gets resolved because it bugs me at night!
